------- Comment #25 from [EMAIL PROTECTED] 2008-05-10 15:53 ------- Aspire 9813WKMi On cold boot fan stop ~1-2 seconds after Grub and after that start(~54°C) and stop(~42°C) OK. After suspend to ram fan spin full speed all the time. After boot: TZ00 = 42°C (fan off) or 54°C (fan on). TZ01 = 41...51°C. After suspend: TZ00 = 27°C. TZ01 = ~35...40°C. acpi_osi="!Windows 2006|Windows 2001 SP2|Windows 2001 SP2|Windows 2001 SP1|Windows 2001" no effect. Does not effect if CONFIG_ACPI_THERMAL or CONFIG_ACPI_FAN is set or not.
